Unable to debug specs

[cec]

Your environment

• vscode-ruby-test-adapter version: 0.8.0
• Ruby version: 2.3.8
• VS Code version: 1.51.1
• Operating System: Ubuntu 18.04 via WSL2 (Windows 10)
• RSpec version: 3.6.0

Expected behavior

Selecting a rspec example group from the test explorer panel and clicking the debug icon should run the example group with debugging enabled.

Actual behavior

I get an popup with the error:

Error while debugging test: SyntaxError: Unexpected end of JSON input
Source: Test Explorer UI (Exension)

In the output panel, if I select Ruby Test Explorer Log I see the following when trying to debug geolocation_utils_spec.rb

I apologize in advance if this is a stupid setup mistake on my end, but I'm new to VS Code as a IDE, since before I could work on a linux desktop and I used RubyMine.

This extensions is absolutely amazing! I can't thank you enough for it.

I have the same issue. Here's a log from the Developer Tools if that's any help:

Can add that I have the same issue using Minitest instead of RSpec.

But then it went away presumably from auto-updates.

~It's back!~

~Does anyone have specific instructions on how to debug the extension? I'd be happy to dig into this.~

Nevermind, there was already a server running on port 1234.

killall ruby

does the trick. And

lsof -i :1234

will find what's using that port on a Mac (or Linux, I think)

[connorshea]

@StefanoDeVuono the Contributing section should have everything you need, I think: https://github.com/connorshea/vscode-ruby-test-adapter#contributing

[tmlane]

I have this issue as well, with rspec

[exocode]

I've the same problem. How can I solve that?

"SyntaxError: Unexpected end of JSON input"

I use the ruby "debug". It only appears when using all tests in a file single tests are working fine

[JordanAtDown]

The problem appear in this function getDebugCommand(debuggerConfig: vscode.DebugConfiguration, args: string) in this specific line -- ${process.platform == 'win32' ? '%EXT_DIR%' : '$EXT_DIR'}/debug_rspec.rb ${args} debug_rspec.rb is not the right file to run. You must find the correct file to run.

[jimjh]

Setting "rubyTestExplorer.debugCommand": "bundle exec rdebug-ide" resolved this issue for me.

I will try to make a PR but I don't have the bandwidth at the moment. Fix is to change this:

https://github.com/connorshea/vscode-ruby-test-adapter/blob/c3ee793cd332306cbe30d9d30363944c8164d3db/src/rspecTests.ts#L191
